Description
DESCRIPTION
Technical Field [0001] The invention relates to industrial means of transportation, in particular, to gravity conveyors.
Background Art [0002] There exists a conveyer (Spiral conveyor, http://wvwv.conveyersystems.ru/catalog.aspx?map_id=112, 05.04.2012 - the closest prototype) which has an inlet and outlet and a multi-loop spiral lane trach around a vertical axis, said lane connecting said inlet with said outlet.
[0003] The known solution has the following disadvantages: • the conveyer lane is movable which reduces durability of the conveyer and leads to extra power consumption; • the conveyer is not suitable to perform any treatment of the load transported on the lane (e.g. assemble, process, etc.), as required by the technology.
[0004] US 2008/184552 A1 discloses a buffer arrangement comprising a slide path (6) for a workpiece carrier (3). Preferably, the slide path (6) is coil-like wound and supported on a central column (15). The slide path (6) comprises preferably at least one slide track (7, 8) and possibly one or several guide tracks (9, 10). The workpiece carriers (3) slide on the slide tracks (7, 8) preferably with the front sides of the centering and clamping bolts disposed on the slide tracks (7, 8).
Summary of Invention [0005] The object of the invention is to produce a conveyer enabling relevant treatment of the loads which is transported on the lane, as required by technology.
[0006] The essence of the invention is that a gravity conveyer with an inlet and an outlet and a multi-loop spiral lane mounted around a vertical axis connecting the inlet and outlet is proposed. According to the invention, the lane is designed as a ferroconcrete surface, each loop of which being square shaped in vertical section and along which movable gravity driven carts are mounted to run in a preset trajectory and overhead manipulators detached from said carts. The manipulators travel trajectory is determined by a guide attached to the lower surface of the lane. The carts travel trajectory is determined by a guide attached to the upper surface of the lane. There are technological stations installed along the lane and the carts and manipulators controlled by a programmable magneto-optical system run and stop relative to said technological stations.
Brief Description of Drawings: [0007] The invention further is illustrated by the drawings, where:

Detailed Description of the Invention.
[0008] Gravity conveyer is a ferroconcrete multistoried industrial skeleton building with horizontal floors (1) which is square shaped in vertical projection, and a multi-loop spiral ferroconcrete lane (2) is mounted around the external perimeter of said multistoried building the first loop of which starts from ±0,00 point level of the production ground floor (3) and gradually goes upwards to reach to the respective level of the top floor. In other way this multiloop spiral lane can be described as a system of mounted ramps. The height between loops (ramps) is equal to floor-to-floor height of the building. Each horizontal production floor of each level of the building constructed in accordance with said design as described herein and each loop of multi-loop spiral ferroconcrete lane has one sector of contact. On said sectors of contact they are mounted in a way that each level of production floor and respective ferroconcrete lane area are linked for necessary technological communication. In vertical projection the entire structure also has a shape of a square (in other embodiments it may have a shape of a circle, an ellipse or a regular polygon to meet required technological process). In the pre-determined location of the structure there is a system of multipurpose elevators (4) to deliver required materials and semi-products to any floor to be used for any required production process. The conveyer inlet is located in the section the ferroconcrete lane mounted on the top production floor and runs all way down around the perimeter of building to reach to the ±0,00 point level of the production ground floor where the conveyer terminates its function. To perform all required technological processes of the plant there are technological stations (5) with various machinery and equipment, including robotized ones, installed along the entire spiral surface of ferroconcrete lane (the system of ramps) and said machinery and equipment being grouped in a way to act as technological stations (5). Guides (6) are attached to the upper and lower surfaces of the ferroconcrete lane and said guides run through said technological stations in a preset trajectory. Said guides provide passage of floor wheeled carts (7) and overhead manipulators (8) though the technological stations. Said carts can move under gravity and the lane (ramps) with insignificantly sloping surface (2° +7°) ensure movement of the carts downwards the lane. Said insignificant slope of the lane does not create inconvenienced for staff working on the lane, however should ergonomic norms have other requirements there is a possibility to bring the staff workplace area to horizontal position. The system in combination (the lane and technological stations installed on its surface, floor and overhead cart-manipulators, upper and lower guides) as described herein makes the gravity production conveyer which is fully controlled by a programmable magneto-optical system to move, stop and park the cart-manipulators at technological stations and other required spots and synchronize technological processes. Given the production and technological requirements and terms of reference main parameters of the conveyer (width, length, angle of slope, the radius of turn around the corners of the building, the number of stations and their locations, guide trajectory, the number of overhead and floor cart-manipulators and their functions, etc.) shall be determined during the design process. For example, in one of the embodiments, given the production requirements if the conveyer lane must be 3.2 kilometers long, 20 meters wide, the angle of slope of the lane (ramps) must be 2° degrees, then a building with square layout will be designed with one side to be 100 meters long, and floor-to-floor height to be 8.5 meters, and the building must have 8 floors, the total height of the building must be about 70 meters, the total production area will be equal to 80,000 m2.
[0009] Technologically the structure as described hereinabove will have the following operational diagram.
[0010] The conveyer is the general assembly line of production which work starts from the top floor level and terminates on ±0,00 point level of the production ground floor. During this process products manufactured on each floor of industrial building are delivered to the general conveyer and assembled on the final products transported by the conveyer, in addition to that the stock of products on each floor are intended for the assembly work done on that particular floor. Production process organized in accordance with this diagram significantly reduces energy resources, several times reduces the land area under production, it is very flexible and compact. For example, if necessary every cart can be dismounted from the conveyer, replaced, or undergo additional technological processing on any production floor and returned to the conveyer. Depending on the width of the lane (ramp system) it is possible to install two or more parallel assembly-lines to double the conveyer productivity. In-plant transport may travel on the lane to deliver such products and equipment to production floors for which elevators are not suitable. Should there be any seismic or other restrictions for the height of the building which will limit the length of conveyer then two or more such buildings may be constructed and interconnected by passageways and galleries on the relevant floors to ensure their technological communication.
